Conjunctival Cysts as a Complication After Strabismus Surgery

Purpose: To identify possible factors associated with the development of a conjunctival cyst after surgery for strabismus. Methods: A descriptive, longitudinal, and retrospective study was done including 12 cases from the past 20 years presenting a conjunctival cyst as a complication of strabismus surgery. Variables included age, sex, eye and muscle operated on, surgical technique used, surgeon, type of suture, and type of conjunctival incision. Fisher's exact test and Pearson chi-square test were used for statistical analysis. Results: The incidence of conjunctival cysts was 0.25%. Although ultimately statistically significant differences in the variables studied could not be demonstrated (P > .05), a greater incidence in the development of this complication in young patients who underwent recession (58.3%) as the surgical technique was observed. Conclusion: Recession may be a risk factor in the development of a conjunctival cyst caused by the high frequency of dragging Tenon capsule during this surgical technique.
